Since some people will probably bash living in a Pokeball 99% of the time, here's a quote to comfort you:

Furthermore, while it is not known how a captured Pokémon perceives their time inside their Ball, the device is said to replicate a "Pokémon-friendly" environment that is "designed for comfort". All of these factors strongly discourage Pokémon from escaping their Balls. - Source

So it's probably rather chill and nothing to worry about. Not sure I want to be one though.
